CEDEC footpath gravels form a firm but porous structure that retains moisture yet allows any excess water to flow through. The materials used are specially graded decorative aggregates, ideal for areas where the traffic is too heavy for grass but where a natural appearance is desired.

Colours

CEDEC gravels are available in three colours: red, gold or silver. The red was the first product developed in the CEDEC range, following a request during the construction of Canary Wharf for a footpath gravel that was free of limestone so as not to affect the pH of the soil around the trees. It was suggested that it should be something like the surface upon which the French play boules.

Following extensive research and development two British aggregates were found to have the correct grading and shape profiles to pack efficiently and they became CEDEC Red and CEDEC Gold. CEDEC Red was chosen for Cabot Square at Canary Wharf. It worked well and in response to demand from other designers CEDEC Silver was developed to complete the range.

Composition

CEDEC footpath gravels comprise of granite or quartzite, which are chemically inert, durable and will not affect the pH value of the surrounding soil. This is important where newly planted trees or pH-sensitive plants are sited. They are very porous materials; they pack but they do not set.

Installation

In order to function effectively, CEDEC needs to be rained upon and walked upon. It will not be effective indoors or under permanent shelter. Rainwater will percolate downwards, so there is no need for surface water drainage systems. CEDEC must not be laid on concrete or any other non-porous base unless a special drainage layer is incorporated into the design.

Coverage is approximately 10m2 per tonne. Compaction is around 25%.
